@jackoneill Thanks for that, then indeed I tested with the current kernel driver. Now testing rtw88-dkms-git for a few hours and so far it works great. If the system crashes then i'll report here.

The driver that comes with the kernel is called rtw88_8821ce (and rtw88_{8821c,pci,core}). The driver in the rtw88-dkms-git package is called rtw_8821ce (and rtw_{8821c,pci,core}). The driver from the kernel seems to have higher priority. So the file in /etc/modprobe.d/ needs to contain these lines:

blacklist rtw88_8821ce blacklist 8821ce

@jackoneill I just installed rtl88-dkms-git, removed rtl8821ce-dkms-git, unblacklisted the rtw88-driver. Rebooted, system froze within an hour. I didn't know how to verify that the driver from the package is used, and not the driver supplied with the kernel? Oh, and the system seemed to use excessive cpu as well, but not sure.

@senorsnor and @Spixmaster: The patch set called "rtw88: add scan notify to firmware and refine fw_feature check" may have fixed this problem. I've been running commit 6ccdad5a58e18eac6b1335f05f94bf2b36146e00 from lwfinger/rtw88 for 3 days now with no freeze. It was impossible to go more than a few hours without a freeze before these patches. Maybe test it? I used the rtw88-dkms-git package.

@jackoneill I see you reported this as a bug, thanks. My system has become completely unusable by now and I'm back to @tomaspinho's driver ..

I too have had problems with the native kernel driver. Although my system didn't freeze I found the wifi connection slow and very unstable as was bluetooth. I kept losing the connection and having to reconnect. When I re-installed this package everything was stable and reliable. I tried switching between the kernel module and this three or four times just in case it was some other cause but I'm pretty sure the instability was down to the native module.

@jackoneill thanks! Output from my two system freezes at https://pastebin.com/9ddkyDCS and https://pastebin.com/dUWxB7B8 . Pastebin files expire after one day so please save it yourself; if you need it after they expire just let me know.

@senorsnor and Spixmaster: Could you post the output from "sudo journalctl" from a single boot that resulted in a freeze? All the text from booting up to the freeze.

I'm going to report this bug at the linux-wireless mailing list and I want to include as much information as possible.

I just upgraded my kernel and removed this driver. Ran an internet speed test and the whole system froze; hard reboot, opened chromium and immediately the whole system froze; hard reboot and now it seems to be working fine. I'm not too positive about all this, keeping an eye on it.

I too have serious issues.

First of all, I do not need this driver anymore. My WLAN card seems to be supported by Linux kernel 5.12. I do not know anything about RFE which is mentioned regularly with this driver. I can just tell you that the driver for me is provided natively by the kernel.

Although, it connects it causes crashes after that. Sometimes immediately and the other times after a few minutes. The errors are solved if I turn off the wireless connection. By crash, I mean that the whole system just freezes and does not react anymore.

Unfortunately, I need to use LAN for some time. I hope that this will be fixed soon. Another solution is to blacklist the kernel provided driver.
